1. Claim.

My invention relates to improvements in implements which are used forterracing the sides of hills to break the force of water coming fromheavy rains, making drainage ditches and terracing the sides of roads.

Further objects are to so construct an implement, that by its use, dirtmay be moved either to the right or left side of the machine as desired,and may be adjusted for so doing with the utmost ease; also to provideready means whereby the terracing blade may be lifted from the surfaceof the ground, and also may be adjusted at any angle of inclination formoving dirt in the process of terracing and making drainage ditches.Still further objects are to construct a terracing machine that shall besimple, substantial, durable, light in weight, cheap in cost ofmanufacture and also be easy to pull.

I attain these objects by the machine illustrated in the accompanyingdrawing in which Figure, 1 is a perspective view of the terracingmachine.

Figure 2 is a perspective view of a device to be attached to either sideof the machine shown in Figure 1 for the purpose of preventing themachine sliding side-ways on steep surfaces.

Figure 3 is an enlarged view of a cog device shown in Figure 1 on lineAA.

Figure 4 is a horizontal cross-section view on the line BB Figure 1.

Figure 5 is an enlarged view of ratchet segment I4" and tilting lever l4shown in Figure 1.

Figure 6 is an enlarged view of the front portion of the machine frame.

Referring to Figure 1, terracing blade I is made of steel with a sharpedge next to the ground. Each end of said blade I is pivotally connectedat 2 to a pivot block 3 rotatably mounted on the lower end of standard4. The bolt 5 pivotally secures the lower end of standard 4 to the frontend of blade carrier 6. The blade carrier 6 is pivotally connected toside bar I at and in front of transporting wheel 8, which is rotatablymounted as shown in Figure 4. Said wheel is secured in place by bolt 8which passes through fork side 9' and secured on the front end portionof outer runner 9 in Figure 4.

Referring to the upright standard 4 in Fig. 1 extending from 8' to l3,cog device AA, curved beam l3, standard 4, and crank 12 shown in Figure1, it will be seen that the lifting crank I2 is revolubly mounted on thecurved beam at I l" and on the upright standard at l2. A cog device(Fig. 3) is provided by means of which the standard 4 is raised orlowered by turning crank l2. This combination of parts raises or lowersthe terracing blade I in Fig. 1 to which it is attached. A similardevice is provided for raising or lowering the other end of theterracing blade.

Referring to Figure 1, the curved beam 39 is pivotally connected by aclevis 2| to the upper end of standard 22. The power to pull saidmachine is attached at 4| by reason of the curvature of beam 39 themotive power pulls downward and forward thereby forcing the terracingblade I downward and into the ground, which together with the weight ofthe machine furnishes the power to force the terrace blade into theground, and does away with the necessity of building a heavy machine.The auxiliary curved beam 13 and corresponding one on the opposite sideof the machine together with the brace bars I0, 20 and 24' brace theframe of the machine. The curved beam 39 is further braced by two chainsattached to the double tree at 40' and 42 and extending rearwardly andattached at the top of standard 4 and to the corresponding standard onthe opposite sides of the machine. I

Referring to Figure 2, this is a device to prevent the terracing machinesliding sideways on sloping ground. It consists of a runner 36,-a bar 34with holes at 33 and connecting braces 31. This device may be attachedon either side of. the base of the machine by bolting 33 (Figure 2) to32 (Figure 1), and hook 35' (Figure 2) in link 35" (Figure 1); and whenso attached the runner 36 runs in the bottom of low places and preventsthe machine from sliding sideways. Hook 23' pivotally mounted on centralbar when placed in a selective aperture of crossbar 3| advances one sideof base bar I' and. shifts the terracing blade into various obliquepositions by putting hook in the different holes of cross-bar 3|.

The cross-bars 3|, 3|, 3i", 20 and III are all pivotally connected attheir ends by reason of which hook23' can be put into any of the holesin cross-bar 3|.

Referring to Figure 1, the ratchet segment [4", lever I4, and rod l5connected to the lower end of lever l4, constitute an actuating meansfor cross-bar H; the latter sliding back and forth by means of a slotmounting in the top central beam 26, as lever I4 is moved back andforth. The ends of cross-bar I 1 are connected to rods extending topivot connections 19 at opposite ends of the terrace blade I. Thisconstruction permits movement of the terrace blade I.

There are four wheels on this machine marked 8 and 28 and correspondingwheels on the opposite side of the base for the purpose of moving themachine.

Figure 4 shows that the wheels are solid rollers With four discsattached to the outer side of said rollers. As said discs extend abovethe rollers, therefore the discs cut into the ground and prevent themachine from sliding sideways.

In operation, the operator hitches the motive power-mot shownto doubletree 4|, tilts the top of terracing blade I either backward or forwardby lever l4, raises or lowers the terracing blade I by means of crank I2and corresponding crank on the opposite side of the machine. The hook 23is placed into the holes in bar 3!" for the purpose of giving theterrace blade I the desired position in order to move dirt either to theright or left side of the machine. The double tree 4| is held inposition by chain 43, and seat 21 is on the rear part of the machine.

Having fully described by invention what I claim as new and desire tosecure by Letters Patent is:

In a machine of the class described the combination of a horizontal baseframe, a terracing blade supported for adjustment at the front of theframe, vertical standards fixedly supported at the forward portion ofthe base frame, upright adjustable blade supports located between'thevertical standards and the terracing blade, means pivotally connectingthe blade to said supports for tilting movement thereof about ahorizontal axis, an operating lever mounted upon the base frame,mechanism operatively-connecting said lever with said blade forefi'ecting a tilting adjustment of the blade about its horizontalmounting axis, upper and lower link members supporting said bladesupports for vertical adjustment and having pivotal connectionrespectively with the vertical standards and with the base frame,actuating means including rack and pinion mechanism operativelyconnected with the blade supports and the vertical standards foreffecting a vertical adjustment of the blade.
